A short message to all WordPress-bloggers: The actual security update version 2.3.3 is strongly recommended. Here at codedifferent no problems occure while upgrading.
Taking this upgrade as an opportunity – the anti spam plugin was also exchanged: In the future every commentator at codedifferent has to prove to be a pattern recognizing human. And by using the reCAPTURE-plugin we aditionally help others: The CAPCHA codes used here are not only some generated graphics – they represent words which could not be recognized by OCR-software. reCAPCHA was developed from Carnegie Mellow University and they actually support the project Internet Archive.

That’s a big one: It really looks like Steve Ballmer want’s to get into the search engine and online advertisement market. Today, Microsoft announced, that the company proposes the acquisition of Yahoo! at a premium of 63% to the current trading price.
It’s a teamup for competing Google – but we’ll have to see whether this transaction will be allowed by the anti-trust authorities and whether joining the forces of Microsoft and Yahoo! development teams will lead to innovation as they want it to be.
How should we call that company in the future? Microhoo!?

P.S. I hope they’ll now hire Ms. Dewey for the future Microhoo! search engine

The people at Skyhook Wireless really did a smart job with their Wi-Fi Positioning System: They just use the highly distributed public and private Wi-Fi infrastructure of everyone as reference points for their location tracking. So basically every WiFi-enabled device can use their technology if Skyhook Wireless scanned and located the hotspots that specific area.
I did not find any competitors, yet. Sure, there are companies like innerwireless with their PanGo location management software, or Cisco with their Wireless Location Appliance, or the Finnish ekahau working in the field of Wi-Fi locating technology. But they all focus on closed business solutions where a dedicated infrastructure is used for tracking.
So the Skyhook Wireless WPS solution looks like an innovative and unique way – and an interesting way to realize navigation and location based services in metropolitan areas. Opening up their API for web developers was a brilliant idea – so let’s use it.

No need for handheld GPS devices which do not function properly in metropolitan areas

The cooperation with Apple in terms of iPhone and iPod touch also effects the Mac now: Today, Skyhook Wireless released their Loki 2.0 Firefox toolbar for Mac OS X and Windows XP. Now it’s possible to check the own location with Loki – if there are enogh WiFi-hotspots in reach known by Skyhook Wireless.
Quite amazing technology with a JavaScript-SDK for Web developers, too.

Steve Jobs presented a new feature of the iPhone – and also the iPod touch. Especially the iPod touch transforms into a new category of devices by adding location based services: By cooperating with Skyhook Wireless it is possible to get the own location by triangulating the signals from different WiFi-hotspots. The iPhone uses also the well known method by using the cell-ids to find the current location. It’s quite interesting, that it seems that Apple is not cooperating with the mobile network operators to get the location by cell ids and triangulation: They realized this feature by cooperating with Google. When I think of the hurdles to realize mobile Location Based Services (LBS) with the different operators … this is not a bad idea.
We really can be curious, whether the iPhone SDK will be the kickoff of a new era in LBS. Maybe Apple will also provide the iPhone web developers with the LBS-SDK Loki SDK for their web applications – that would really roll up the LBS-scene
